Bleeding penis while sex

I was having sex without condom and after we finished I saw that I had light pink discharge and I thought I was bleeding. I’m really small and sometimes that happens (tears). But then I saw that the tissue that the guy cleaned his penis with was bloody. Maybe he was the one bleeding?! We’ve been together for months and this has never happened before. I don’t know why I didn’t ask him if he was bleeding. Now I’m concerned. If he was bleeding maybe he has an infection or smth. I feel like I can’t ask him now. What do you think?!

(His semen wasn’t bloody at all)
